-- Parse raw arguments. A single parameter `data` is passed in, with the following fields:
-- * `raw_args`: The raw arguments to parse, normally taken from `frame:getParent().args`.
-- * `extra_params`: An optional function of one argument that is called on the `params` structure before parsing; its
--   purpose is to specify additional allowed parameters or possibly disable parameters.
-- * `has_source`: There is a source-language parameter following 1= (which becomes the "destination" language
--   parameter) and preceding the terms. This is currently used for {{pseudo-loan}}.
-- * `ilang`: If given, it is a language object that serves as the default for the language. If specified, there is no
--   language code specified in 1=; instead the term parameters start directly at 1= (or at 2= if `has_source` is
--   given).
-- * `require_index_for_pos`: There is no separate |pos= parameter distinct from |pos1=, |pos2=, etc. Instead,
--   specifying |pos= results in an error.
--
-- Note that all language parameters are allowed to be etymology-only languages.
--
-- Return five values ARGS, ITEMS, LANG_OBJ, SCRIPT_OBJ, SOURCE_LANG_OBJ where ARGS is a table of the parsed arguments;
-- ITEMS is the list of parsed items; LANG_OBJ is the language object corresponding to the language code specified in 1=
-- (or taken from `ilang` if given); SCRIPT_OBJ is the script object corresponding to sc= (if given, otherwise nil); and
-- SOURCE_LANG_OBJ is the language object corresponding to the source-language code specified in 2= (or 1= if `ilang` is
-- given) if `has_source` is specified (otherwise nil).
